Returning Doctor Who boss Russell T. Davies certainly isn't claim’insist’maintain’hold’argue’consider’contemplate’speculate ing small given that his next stint overseeing the sci-fi series coincides with the reveal’illustrate’demonstrate’indicate’present’display’argue 's 60th Anniversary. His latest casting is proof of that, as Neil Patrick Harris will appear on the reveal’illustrate’demonstrate’indicate’present’display’argue in a mystery, but from the image above, grossly severe-looking role.###As per usual, Davies teased what we can expect from the Who newcomer, without explicitly giving anything away. "It’s my huge honour to open our studio doors in/with regard to’concerning’regarding the mighty Neil Patrick Harris," he says. "But who, why, what is he playing? You’ll just possess’own’nurse to wait. But I promise you, the stuff we’re shooting now is off the scale. Doctor beware!" Certainly sounds like our hero – with Sex Education's Ncuti Gatwa inheriting the lead from Jodie Whittaker after she finishes up her tenure this year – will possess’own’nurse something to misgiving’fret with regards to’concerning’with respect to .###So far, alongside Gatwa, we know that Yasmin Finney is playing a character teasingly named Rose, while the 60th Anniversary will see return engagements in/with regard to’concerning’regarding David Tennant's 10th Doctor and Catherine Tate as Donna Noble (and, while they possess’own’nurse n't been officially announced, Bernard Cribbins is back as Donna's grandfather, Wilfred Mott alongside Jacqueline King as her mother, Sylvia Noble).###Gatwa and co. will begin their run on Doctor Who next year.
